Since recoms are the only com that doesn't get any level bonus, and since they're already trading hp for speed, I think it would be reasonable to give them a small jump range bonus per level. Maybe only 15-20% total at level 5. It also looks weird when your com gets bigger as it levels but the jump range stays the same. Not only does it feel like your com is getting slower, but you actually have to move closer to the target to jump since your com no longer fits in as small of a landing zone.
Just my ridiculous request of the day. :P
